BEARING AND BEARINGBOX.

Specification of Letters Patent.

Application filed November 4, 1904.

Patented Jan. 17, 1911.

eriai No. 231,364.

To all whom "it may concern:

Be it known that I, EDDY R. lVi-IITNEY, a citizen of the United States, residing at Lynn, county of Essex, State of Massachusetts, .have invented certain new and useful Improvements in Bearings and Bearing-Boxes, of which the following is a specification.

My present invention relates to journal bearings and the boxes in which they are supported and consists in certain novel and useful features of construction and arrangement whereby a highly reliable and ellicient bearing and box therefor is obtained.

The various features of novelty of my are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of my invention, however reference may be had to the accompanying description and drawings in which I have described and illustrated one form in which my invention may be embodied.

- Of the drawings, Figure 1 is an elevation with parts broken away and in section show- 111g an electric motor equipped with my invention; and Fig. 2 is an end elevation of the motor shown in Fig. 1 with parts broken away and in section on the line. 22 of l ig. l.

.ltejlerring to the drawings, 1 represents the lield ring of an automobile motor having end members or heads 2 and 3 secured to its ends. Each of the end members is formed with a large centrally located aperture in which the bearing box members 1- and respectively, are secured as shown. Each of the end members is rabbeted at (3. to. form a supporting surface against which a circular flange? integrally formed on the correspomling bearing box member may iind a seat. The bearing box members are secured in place by clamping members i. and clamp ing bolts ll tapped into the end members. \Vith thisconstruction the bearing boxes are angularly adjustable in the heads in which they are supported.

lhcbean'ing box members 4 and 5 are substantially identical in construction though in the coustriu-tion shown in Fig. 1 the right hand bearing is slightly smaller than the left. Ilach bearing box member comprises a substantially cylindrical chambered portion 7 which forms the bearing box proper. The flanges 7 extend from the il l l t l l p proper by 1 1.

periphery of the portions 7. The bearing box members are preferably formed out of cast metal, cast iron being ordinarily employed for the purpose, but when lightness is desirable aluminum may be employed.

The cylindrical portions 7 of the bearing box members are eccentrically placed with respect to the flanges 7. Openings substantially concentric with the flanges 7 are formed in the ends of the cylindrical portions T. In each portion 7 a cylindrical bearing sleeve 10 formed of suitable material is supported in line with these openings in a cylindrical support 11. Each support 11, which is preferably integral with the walls of the box member in which it is supported, is connected at its ends to the ends of the box proper. The lower portion of the sup portis connected to. the bottom of the box two substantially vertical webs The upper portion of the cylindrical support forms part of the upper wall of the box.

ltlach bearing sleeve 10 is provided at its inner end with. an integrally formed collar 15 which abuts against the inner end 0f the sleeve support L1. Each sleeve 10 is held in place by a screw 16 tapped through the up per portion of the SlBOVdSHPPOITl) with its lower end entering an aperture 17 formed for the purpose in the sleeve 10. As shown there are two apertures 17 formed in each sleeve 10 at points diametrically opposed.

Two similar oil and waste containing pockets 18 are formed at opposite sides of each sleeve support 11 by the walls of the box proper and the sides of the support 11 and the webs 14:-' Openings 19 which may be substantially rectangular are formed in opposite sides of the support; 11. Each bearing sleeve 10 has an aperture or opening 20 termed in one of its sides. The bearing sleeve lt shown at the left hand end of Fig. l and in Fig, i is arranged so that its aperlure it regi ters with the left hand aperture it) as seen in Fig. 3. As thus arranged the hearing for the left: hand end of the arma ture shaft :-?l as seen in Fig. 1 is lubricated by oil and waste contained in the left hand pocket 18. With this arrangement it is as sumed that the side thrust usually found in constructions of this character is suehias to cause the armature shaft to be forced against the right hand side of the bearing 'sleeve shown in Fig. 2. When the side thrustis'in,

A plug 26 is reniovably secured in an opening iiia'med in the ho. tom of each oi? these chambers through inav be renmved from time which wa e on to time. in order to p c cut the accun'nilalion of an undue amount of oil in the chamber 25, a drain plug 2? is also tapped into the lI'UllUlll of each chamber. The plugs 27 are hollow and are formed with openings 28 at their upper ends comnmnicating with the bores oi" the pin" When the level. of oil in either chamber -5 rises to a predetermined height any excess of oil in the chamber will flow out through the opening 28 and the hollow in the corresponi'ling plug 27. Downwarillv inclined flanges or webs are lo- "ed in each chamber extending between webs l-l from opposite ends of the box nearly half the length of the box. 'llhese ttllUW of the accumulation of a large or oil in each chambe while preventing the oi from moving out. of the lower end of the l unbcr 253 when the motor tilted out. ot its normal horizontal position.

.55 shown the armature shatt 21 is provided with a flange or collar 30 adjacent inner end of each bearing sleeve 10 which serves to throw any oil which may out between the shaft 2t and the sleeves t the inner ends of the latter, into chanor spaces 31 surroiunlii'lg the flanges 30. A. similar channel or space 39 is formed at the other end of each bearing box in which oil which lealzs out between the shaft and sleeve at the outer end of the latter may be collected. The en passing into the channels or spaces 3i and 3; in each boa; carried to the ash: oil chamber by the flanges 29.

The apertures at the outer ends of the bearing boxes are threaded. A plug 3st is secured in the threaded aperture in the right hand end of the right hand bearing box as seen in Fig. l. Rings 35 and packing ill are secured in the threaded a perturc in lhe left hand end of the lel'l hand linraring box. thus forming a stalling box to prevent the passage of oil along the shaft. .21 which projects through this end of this bearing box. This stuliing ho also prevents the entrance o'l' dirt into the hearing from the exterior.

will be observed that the only chance for dirt to enter the left hand bearing box as seen in Fig. l, is through the stalling box and umlerneath the cover plate '5. The only chan tor dirt to enter the right hand bearing boa; as seen in Fig. l, is under the cover glate 23. The only paths lfor oil to leak out of the pockets 18 are between the bearing sleeves l0 and the shaft 21 and between the bearing sleeves .lt) and-the corresponding supports 11. When the bearings are propcrb constructed it. is found that the oil leakage out of the pockets 18 is very slight.

' What I claim as new and desire to secure by Letters Patent ot the United States, is,-

1. In combination, a shafthaving a side thrust exerted upon it, a bearing box pr0- vided with a pair of accessible pockets containing lubricating material, bearing sleeve having an aperture formed in one side and adapted to 0 Ten into either of said pockets and. means for securing the sleeve with the aperture opening into one of said pockets depending upon the direction of the side thrust said means being accessible from the exterior of said box.

2. A bearing box formed with two accessible chambers containing lubricating material and provided with a bearing sleeve support located between said chambers, said support having apertures formed in opposite sides and coinnnuiicating with said chambers, a bearing sleeve having one aperture formed in itand adapted to open into either of said chambers, a shaft having a side thrust exerted upon it journaled in said sleeve, and means for securing said sleeve in said support so that the aperture in the sleeve registers with one of the apertures in the support depending upon the direction of the side thrust, said means being accessible from the exterior of said box.

3. In a bearing-box provided with a. pair of accessible pockets containing lubricating material a shaft having a side thrust exerted upon it, a bearing-sleeve having an aperture formed in one side, and means for securing the sleeve with the aperture u ening into either of said poclrets' dependent upon the direction of the side thrust, the aperture being arranged on the side of the bearing op osite to that which receives the exterior of said box.

4. In a bearing-box provided with a pair of pockets containing lubricating material, a shaft having a side thrust exerted upon it, a bearing-sleeve having an aperture formed in one side,' and a screw accessible from the exterior of said box for securing the sleeve with the aperture opening into either of said pockets, dependent upon the direction of the side thrust.

5. In a bearing box provided with a pair of pockets containing lubricating material, a shaft having a side thrust exerted upon it, a bearing-sleeve having an aperture formed in one side, a screw for securing the sleeve with the aperture opening into either of said pockets, dependent upon the direction of the side thrust, said pockets having an opening through which the lubricating material is introduced, and a plate for covering said latter opening and the head of the screw.

6. A bearing-box formed with a pair of pockets containing lubricating material and provided with a bearing-sleeve support lo cated between said pockets, said bearingsleeve support being provided with two chambers separated by an inclined wall having an opening in its lowest portion one of said chambers being arranged to receive waste oil from the bearing and deposit it into the other chamber through themsaid opening and said inclined Wall serving to prevent the return of the waste oil when the box is tipped out of its normal position.

In witness whereof I have hereunto set my hand this 28th day of October, 1904,
